SPALDNG & BROS., OF JERSEY CTY, NEW JERSEY, A. CORJORATION F NEW iJERSEY GOLF-CLUB IRON.

To NZZ i12/10m.. t may concern.'

Be it known that I, Hanni' K. B. DAVIS, a citizen ot the United States,and resident o't Holyoke, in the county of Hampden and State oi"Massachusetts, have invented certain new and vuseful improvements inGolf-Club Irons, of which the following is a specification.

My present invention relates to improvements in golf iron heads (otherthan putters) and aims to provide a head which will have added weightfor the purpose of otering the greatest resistance to the shock of theblow or ball impact, and to which weight is produced by a protuberanceor bulge on the striking face of the club arranged in such a manner asto minimize faulty strokes which are productive of slices and hooks.

It is well known among golfers that there is a sweet feel in every head.This point moves forward or backward according to whether the head islong and thin, or short and wide. It is the object of this invention tolocate that sweet point and to associate it with the extra weighting ofthe blade referred to above.

It is a common fault with the average golfer in making his stroke, tohit the ball with the club face at an angle other than a true rightangle to the intended line of the balls flight; at times the hands aretravelling ahead of the head of the club, with the result that the bladeat the time of impact is turned out to an angle to the right of thedesired line. At other times the reverse happens, the action of twistingthe head over so as to have the blade turned to the left, the result ofthe irst named fault is a ball curving to the right, the result of thesecond, a ball turning to the lett.

These faults are minimized by 'my improved club head, and at the sametime greater driving torce is secured by the means which accomplish suchresults and without weighting or altering the back Jface oit the club. i

In order that my invention may be better understood, reference is madeto the accompanying drawings, in which Figure l is a face view of thehead of a golf iron. n

Fig. 2 is a section on line 2-2 of Fig. l;

Serial No. 705,917.

Referring by reference characters to this drawing, the club as a wholeis indicated at 5 and is intended' to be representative ot any golf ironother than al putter, such for example driving iron, mid-iron, mashie,and niblic, and the various intermediate clubs. The `driving face la ofVthe club head is provided with a bulging portion a, the highest pointofV which coincides with the proper ball impact point. It will befurther noticed lthat this bulging portion is oit part cylindricalshape, with the longitudinal axis thereof running perpendicular to theclub face.

In other words, the face of the club is straight at any and all points,taken vertically, and has a convex curved portion a, which would appearthe same in every section taken parallel to section 2-2- lt will benot-iced further, that the bulging or convex portion is confined to theclub face adjacent the impact point, the remaining portions of Vthe clubface eX- tending in substantially straight and slightly inclined linestowards opposite ends of the club head.

The operation and advantages of my improved club in correcting orminimizing faulty strokes resulting in pulls or hooks and slices, willbe clear from the diagram, Fig. 4. y

In this figure, arrow line l indicates the path of the club in making aproper shot; line 2, an' exaggeration of the path of travel on aAslice-producing shot; and line 3, a

Vsimilar indication of the path of travel on a hook or pull producingshot, it bein understood that in a slice shot, the Aclu head travelstowards the player and in a hook shot, the reverse.

Line A represents the straight tace of a club of customary form inmaking a proper shot, the lines A and A2, the corresponding positionsfor slice and hook respectively; while curved line B represents the:position of the curved tace of my improi'fed club head in making aproper shot, and B and B2 the corresponding positions for slice andhookf y vC and C represent the hall inipact points ttor surface lines Aand B respectively (slice shots With plain and curved face clubs) andarrow lines A3 and B3 indicate the difference in directive influence onthe ball; v In a similar n'ianner C? and C4 indicate ball iinpactpoints-tor a hook shot, and A4, Bfthe corresponding directioninfluences.

Referring' toV hallinipact point' C of club facevA", it Will be readilynoted that it the club is" drawn towardsv the player, side spin startedby' the inclination of the club' Will bein'cras'e'd by such" n'ioveinentwith corresponding Gravatar@ in flight..4 In con'- trast With this, itWill be noticed, 'o'nreference to Contact point C on the cnrved-ace,that the angle of' the curve osets' the action of the side spin'.-

A similar action occurs on a hooked or pulled shot, as Will be clearfrom the diagrani' Having thus described what l claim is y l. A golfiron head having' a' face provided With a ball ii'npact portion which isconvex lengthwise of the club' head, and straight vertically thereof.

2. A golf ron'head having a Weight providing bulge on its front face ofpart cylindrical shape, and extending vertically oi the cluh.

3. A olil iron head having a raised portion on the striking tace thereofextending vertia'lly of the' club head, said tace he ing` rounded 'andthe ren'iaining portions of thefcliib face extending ronisaid roundedportion in' slightly inclined planes towards and to the opposite ends ofthe club.

ln testin'iony whereof, I aix lnv signature.
